Abstract
An endless belt type bench testing apparatus includes a pair of rotary drums, a flexible endless belt wound over the rotary drums and extending therebetween, and a supporting base disposed between the rotary drums and including an operating surface which faces a portion of the belt with a predetermined clearance gap therebetween. The operating surface is formed with a plurality of discharge ports which communicate with a liquid medium supply source for establishing a hydraulic pressure in a form of a liquid medium layer at the clearance gap. An improved structure is included for ensuring effective generation of a dynamic pressure in a form of the liquid medium layer at the clearance gap.
